BRACKET-CLAMP FOR SHINGLING.

E-ECIFECATIQN forming part of Letters Patent No. 337,825, dated March 16, 1886.

Application filed Januar-y 7, 1886. Serial No. 187,850. (No model.)

T0 all 1071/0171, t may concern:

Be it known that I, VILLIAM ERVIN, a citizen of the United States, residing at Argentine, in the county of Vyandotte and State of xgrnKansas, have invented a new and useful Roof- 1o object to provide a bracket clamp of simple construction, of as few parts as possible, and yet be durable and economical.

In the drawings, Figure l is a side View in section of my invention in position on a shin- Fig. 2 is a front elevation of my bracket-clamp. Fig. 3 is a perspective view.

My bracket-clamp, as shown in the drawings, is constructed of two pieces, the bracket A, having the elongated tongue c, and the camzo lever B, pivoted or fulcrumed in the bracket atb. The tongue a is dat on its under side and beveled on its upper side near the end, as shown in Figs. l and 3. The cam-shaped part of the lever B is beveled to an edge, as shown I use steel, castiron, or other material suitable in manufacturing my bracket-clamp- To adjust the bracket to the roof, the tongue a is inserted under the butt-end or loose end 3o ofthe shingle, with the lever perpendicular,

cam -shaped part thereof presses tightly and bites into the shingle, as shown in the drawings.

It is evident that the lever B may have diametricallyopposite cam-shaped projections so formed that the bracket could be clamped to the shingle by pressing the lever B either to the right or lett.

In brackets heretofore constructed the clampinglever has, so far as I am aware, been arranged to swing up and down relative to the slope of the roof, with the effect often of pushing down or out a litt-le Way the tang of the bracket from under the shingle. My device avoids this, as also the danger of splitting the shingle.

l. In a shingle-bracket, the combination of a bracket having a part to run under the butt of a shingle, and a cam-lever swinging to the right or left to clamp the same to the shingle.

2. A bracket-clamp for rooting, consisting ofa bracket, A, formed out of a single piece of material having an elongated tongue, a, and cam-lever B, pivoted or fulcrumed thereto, substantially as shown and described.

In testimony whereof l have hereunto subscribed my name this 19th day of December, 1885.

WILLIAM ERVIN.
